摘要

针对挠性航天器在轨运动过程中挠性结构的持续振动问题，提出了一种基于模糊控制原理的改进型自抗扰控制方法，实现对挠性航天器的振动抑制。通过非线性自抗扰控制器快速地抑制挠性航天器的低频振动，并结合模糊控制实现自抗扰控制器(Auto Disturbance Rejection Controller, ADRC)参数的自整定，提高自抗扰控制器的性能。将仿真结果与PD控制和非线性自抗扰控制进行对比，结果表明该控制算法能更加快速有效地抑制挠性航天器的振动，具有重要的理论研究和工程应用价值。

Abstract

Considering the continuous vibration of flexible structure in the on-orbit motion process of the flexible spacecraft, an auto disturbance rejection control(ADRC) strategy based on fuzzy control theory is proposed, so as to realize the vibration suppression of the flexible spacecraft. The nonlinear auto disturbance rejection controller is designed to quickly suppress the low frequency in the flexible spacecraft, and in order to improve the performance of ADRC, we combine fuzzy control to adjust the ADRC parameters easily. Compared with PID control and the nonlinear ADRC control, simulation results show that the controller can suppress the vibration of the flexible spacecraft more quickly and efficiently, and has important value for theoretical research and engineering application.
